My RV is an Axxess, the other division of Airstream, that has toy hauler capability.
This is a 2014 unit.
I have put 800 watts of solar panels on the front. Right now it is working just charging the 12 volt
I have the 110/220 volt work started but really need a pro to complete it.
I have two inverters that will run from 48 volt batteries.
The shore power connect is 220 volt 50 amp, so two hot legs, one ground one neutral, one hot to each inverter.
I have the transfer switch installed along with a 2500 watt Onan LP generator with auto start.
This is a pretty sophisticated system, with full programmability.
I also have 220 watts of solar on my truck with a 12 volt
100 amp hour lithium battery that connect to the RV. Both the 12 volt
and 48 volt on the RV will be lithium.
